Pivotable tool holder and method of machining a part to be turned on a special-purpose lathe with such a tool holder

摘要

In a special-purpose lathe, the tool holder is designed as an acute-angled circular-sector disc (5) which is pivotable about a horizontal axis (4). The individual tools (6) on the circular-sector disc (5) can thereby be pivoted alternatively right into the turning centre. Furthermore, it is possible to swing up the circular-sector disc so far that it does not collide with a centre drive unit (7) when the cross slide (3) with the circular-sector disc (5) travels past this centre drive unit (7). <IMAGE>
